I have encountered this strange structure a few times in my quest to understanding the Ordovician of Kentucky. It is rarely seen, and I always ignored the thing since it didn’t seem relevant to what I was studying. Though recently, I found a few of these, intimately associated, in what might be a lagoonal environment???*
That grabbed my attention, and I submitted photos of this thing to several well known paleo-researchers. Most had no ideal, but Dr. Young clued me in! Probably, algal balls. He suggested a thin section would be determinate, but I still haven’t cut the thing.
When informed of Dr. Young’s opinion, another researcher concurred, but he hadn’t seen any, this large, from the local biota; one other was skeptical.
So, have you seen anything similar?
These were found in a mud bed, of limited lateral extent(a few meters), interbedded within the calcarenites of the Tanglewood mb. of the Lexington Limestone.
perhaps, that is my familiarity with the barrier islands???
Too, why can't I figure out the code of wordpress?
I’m not a ‘puter geek, but I thought that the site was HTML??? Any suggestions?
